Abstract

A conveyor system has a housing with a plurality of horizontally extending lower support arms and a plurality of horizontally extending upper support arms spaced above the lower support arms and forming a plurality of guide sets. An upper pair of crossed scissor fingers and a lower pair of crossed scissor fingers are provided. A vertically oriented primary pivot shaft is secured between each upper support arm and its associated lower support arm and through each of the scissor fingers for rotation about a common first axis for each guide set. Four vertically disposed guide plates in each guide set with second pivot shafts are pivotally coupled to an associated end of one upper scissor finger and one lower scissor finger for rotation about second axes. Each guide plate has a radially inwardly oriented extension with a slot and fixed pin extending downwardly from an upper support arm into an associated slot. A driving subassembly includes a common drive bar for concurrently moving the common scissor fingers and guide plates between an inoperative orientation and an operative orientation.
